Answer: C. Mode
Step-by-step explanation:
Qualitative data applies to observable data such as reoccurring patterns (mode)
Quantitative data applies to numbers and numerical calculations (Mean, Median)

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -4x² + 6x - 4
f(5) is x = 5
<u>Step 2: Evaluate</u>
- Substitute: f(5) = -4(5)² + 6(5) - 4
- Exponents: f(5) = -4(25) + 6(5) - 4
- Multiply: f(5) = -100 + 30 - 4
- Add: f(5) = -70 - 4
- Subtract: f(5) = -74
Answer:
∠B ≈ 56.25°
Step-by-step explanation:
Since the triangle is right use the cosine ratio to solve for B
cosB = = = , thus
B = ( ) ≈ 56.25°
